Can cutting calories really extend your life? Yes, say a bunch of very old, very hangry monkeys. For years, scientists at the American University of Wisconsin-Madison and the National Institute on Aging ran duelling calorie-deprivation tests on primates, which live to an average age of 25, to see if less food equals longer life. They agreed that cutting calories by 30% improved the monkeys’ health (by cutting cancer and heart-disease risk), but on living longer, they didn’t see eye to eye. But not long ago, they came to their senses, pooled their data, and finally announced this: Yes, eating less upped the monkeys’ life span about 15%, but only if: 1) their calories were restricted starting at an older age (post-teens was best), and 2) they ate whole, non-processed foods. But what constitutes “less food” for primates like us? Calorierestriction cheerleaders advise cutting food intake by about 20%; any more, and — unless malnutrition is your goal — you’ll want to discuss with your doc first.
